Ascentage Pharma (6855.HK), a global biopharmaceutical company engaged in discovering, developing and commercializing therapies to address global unmet medical needs primarily for malignancies, today announced that it has released the clinical data of olverembatinib (HQP1351), the company’s novel drug candidate, in patients with succinate dehydrogenase- (SDH-) deficient gastrointestinal stromal tumor (GIST), in a Mini Oral at the 2024 European Society of Medical Oncology (ESMO) Congress.
These data of olverembatinib, presented in the Mini Oral at ESMO 2024, showed sustained clinical benefit in patients with SDH-deficient GIST. As of March 12, 2024, six of the 26 patients with SDH-deficient GIST enrolled in the study achieved partial responses (PRs). The objective response rate (ORR) was 23.1%, and the median progression-free survival (PFS) was 22 months. Furthermore, studies on mechanism of action (MOA) revealed that olverembatinib exerts its antitumor activity by modulating multiple signaling pathways involved in angiogenesis, apoptosis, proliferation, and survival.
